Jonah and Nahum brought covenant lawsuits against Nineveh/Assyria. Nineveh accepted Jonah’s message and repented. The result: positive national sanctions.
Nahum came over a century later. He said that time had run out for Nineveh. It had. The Babylonians conquered Assyria in the next generation.
Conclusion: Assyria was under God’s law and therefore under the law’s sanctions. God’s civil and moral laws are cross-boundary laws: geographically and temporally.
I gave this presentation to a Sunday school this week. I began with chronology. If you get this wrong, you get everything wrong. This is why higher critics of the Bible begin with undermining biblical chronology.
